I don't know what changed in 1.7.4, but when I run detekt in parallel on all configured modules, I get these weird classloading issues:

Hm, this sounds like https://github.com/detekt/detekt/issues/2501 😞.
Which Kotlin version do you use?

Just to be sure, can you add toolVersion = "1.7.4" to the detekt {..} and enable debug = true . is the version right? Also which Gradle version are you running?

Sorry for the late reply, I'm on vacation right now. I'm on Gradle 5.6.4 and Kotlin 1.3.61 AFAIR, will report back next week. Thanks for the bug link, will star that.
